This Exam FM sample reference tests Bond with Geometrically Growing Coupons. At a half-year yield of 3.1%, the redemption has present value 400.17. The remaining price supports thirty coupons growing 1% each period, which makes the first coupon 113.75 and selects choice B.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A discounts a level-coupon stream and never applies the 1% increase to later coupons.
CChoice C grows coupons at 3.1%, confusing the half-year yield with the contractual coupon-growth rate.
DChoice D omits the discounted redemption value before solving for the coupon scale.
EChoice E uses fifteen annual periods even though both coupons and yield conversion occur every half-year.

Original variant: price a growing-coupon note
A ten-year note pays semiannual coupons. The first coupon is 60, each later coupon is 0.5% larger, and the note redeems for 1,000. Investors require a nominal annual yield of 5% convertible semiannually. Determine the note's price.
A 1,421.66
B 1,506.28
C 1,587.41
D 1,640.05
E 1,706.90
Variant answer in brief
Discounting twenty coupons growing 0.5% per half-year and the 1000 redemption at 2.5% per half-year gives 1587.41, choice C.
